IMPROVEMENT IN TEA. AIil'D COI'IEE-STRAINERS.

The Shedule referred to in these Letters Patent and making part of thesame I, ANDREW B. Snsnmas, of the city and county of Providence andState of Rhode Island, have invented a. new and improved Rim for TeaandCoffee- Strainers, and for other purposes hereinafter described.

The object of my invention is to provide a rim which can be securelyattached to the wire-cloth. or other material of which a strainer forliquid may be composed, by means of a fold on the lower side of saidrim, which shall embrace and hold the edge of the wire-cloth or otherstraining-material, when in-- serted therein. I

Description of the Accompanying Drawings. Figure 1 is a side view of thespout of a coflee-pot,

I with the strainer attached. 1

Figure 2 is a vertical section of the stiainer, showing the folds in therim, and the manner in which the wire cloth or other material isinserted and held in-its place.

Figure 3 is the rim inverted, and showing the open H ing in the fold inwhich the wire-cloth is to be in- I 'serted.

ff; Figure 4 is an enlarged section of the rim, showing the folds andthe wire-cloth inserted in its place. I will describe the mannerin-which the rim embodying my inveutionis made.

Taking a piece of tin equal in length 'to'the circumference of theproposed rim, and of any desired width, 1- turn' two folds, or rather adouble fold, along the whole length of the piece, on the side intendedfor the bottom of the rim. These folds are shown at a, fig. 4, and maybe .formed by first turning up a portion, from one-fourth to one-half aninch in width for an ordinary coffee strainer, and then doubling backagain about one-half of the fold first formed.

This outer fold forms the space in which the edge of the strainer'clothis to be inserted.

Another fold, b, figs. 1 and 4, is made along the other side of thestrip of tin, for the purpose of form-* ing an ornamental ridge or headaround the topof the rim. The piece of tin thus prepared is thenpassedover a roller and formed into a. circular shape with all the folds onthe outside. I

The'space intended to receive the strainer-cloth may be kept open duringthis process by the insertion of a narrow strip of tinbefore forming thecircle,

which must afterward be removed, or the space may be suiiiciently openedafter the ring is made, by passing a thin knife-blade around between thefolds.

The strainer cloth, which has been previously cut and fitted into acorresponding size and shape, is then inserted in its place, and-thefold; is clasped tightly together by means of machinery adapted tothe'pnrpose, and well known-to those skilled'in the art. The strainer isthen completed by applying a very little solder to the edges of the tinbrought together in forming the ring.

The attachments for appending the strainer to the spout ofa tea orcoffee-pot are 'su fliciently shown by figs. 1 and-2. When intended forother purposes, an

ordinary ball or handle may be attached to it.

A strainer constructed in this way presents a perfectly smooth surfaceon the inside, the edges of the wire-cloth being entirely inclosed inthe fold in which it is inserted; 4

My invention also obviates the necessity .of using solder to fasten thewire-cloth to the rim, which is done in the case of nearly all thestrainers now in use, while the folds around the bottom of the rim giveit an additional strength and firmness very desirable in many articlesto which it is adapted.-

My invention is applicable to all tea and .coii'eestrainers, and otherliquid strainers, whether with bails or handles, andwhether wire-clothor other straining-material be used, and also; applies to'other articlesof the same general form in which wirc cloth is attachedto a metallicrim.

I claim as my invention- A rim for strainers, the two folds runningaround the bottom thereof, substantiallyas described, and for thePurposes specified. v
